The Yamaha YSL-456G is a dual bore tenor trombone that was originally available only in the Japanese domestic market. It features an 8" gold brass bell, traditional wrap F-attachment with rotor valve, and a medium dual bore handslide (.500"/.525"). This design gives the player the projection and low-register range of a trigger trombone, while maintaining the ease and efficiency of a smaller bore horn. For players stepping up from a straight tenor, this is an ideal transitional instrument.
This specific example is in extremely clean condition — a one-owner horn that has seen only minimal use. It has never been damaged or repaired, and it shows virtually no wear on the contact points, lacquer, or valve hardware. It has just been professionally cleaned and serviced, so the slide and rotor action are smooth and responsive. Everything functions properly and needs no adjustment or follow-up work.
The YSL-456G is often compared to the YSL-446G, which is sold in the U.S. market and currently retails for over $2,000 new. In most respects, the 456G is identical — a quality, dependable horn with Yamaha’s renowned consistency and build quality.
✅ Who is the Yamaha YSL-456G best suited for?
This is an excellent choice for an advancing student — especially middle or high school players who want to begin using a trigger trombone but aren’t quite ready for the weight and air requirements of a full .547" large bore model. The dual bore design gives them more flexibility while keeping the feel approachable. It’s also a solid option for adult players returning to the instrument who want a responsive, mid-sized horn without overspending.
This instrument has been sold and is now shown here as a historical reference for trombonists and collectors.
